Configuring a HTTP (S) reverse proxy or TCP port forwarding The reverse proxy capability allows applications that are unable to configure HTTP (S) forward proxying to address the proxy directly and have it forward these requests to a configured destination, which is also applicable for forwarding TCP-based communications. When those computers make requests to sites and services on the Internet, the proxy server intercepts those requests and then communicates with web servers on behalf of those clients, like a middleman. On localhost this is a tougher issue since we want to avoid forwarding loops (packet is diverted to Squid but it should be sent to the Internet when Squid done its thing).

AWS Global Accelerator and Cloudflare Spectrum are examples of TCP proxies you can pay to use in the wild. In this test, we configure haproxy to use the kernel's splicing feature to directly forward the HTTP response from the server to the client without copying data. This policy only allows outbound TCP and UDP traffic, but it also monitors that traffic. Its job will be to listen for data sent from your phone; forward it to the real, remote server; and finally forward any responses from the server back to your phone. For macOS devices the feature is introduced since version 5. It poses a challenge if the upstream server needs to determine the true origin IP address of the connection or session, for purposes such as authentication and access control, rate limiting, and logging.
